About this tool
Code Review Cycle Time Calculator
The Code Review Cycle Time Calculator computes total cycle time, DORA tier classification, and reviewer load from PR open-to-merge timing data.
• Measure code review cycle time for a DORA lead time calculation
• Assess whether current review throughput keeps up with PR volume
• Identify whether wait time or revision time dominates review cycle
• Set a 24-hour first-review SLA based on current reviewer load

FAQ
What does this tool tell you?
The Code Review Cycle Time Calculator computes total cycle time, DORA tier classification, and reviewer load from PR open-to-merge timing data.
What affects the result most?
Review cycle time: time from PR open to merge — DORA lead time component. P75 target: Elite teams <1 day, High teams <1 week — DORA benchmarks. Review wait time: if reviewer has >10 open review requests, review queue blocks flow.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
